### Here's the first 20 in better form

Customer:

never mind it looks worse. sorry

Ray Atkinson :

I have them already. I am on #4

Ray Atkinson :

I tossed it into a Word file and cleaned it up. I am used to doing that.

Ray Atkinson :

Please check question 6. I cannot read it properly. What is the log base?

Customer:

log 12 554

Ray Atkinson :

Thanks.

Ray Atkinson :

#12 does not look right. Is there something missing?

Customer:

[IMAGE][SRC][/SRC][ALT][/ALT][WIDTH]100[/WIDTH][HEIGHT]100[/HEIGHT][STYLE][/STYLE][/IMAGE]

Ray Atkinson :

eh?

Customer:

log2x+log2(x-6)=4

Ray Atkinson :

log2(x)+log2(x-6)=4 is correct?

Ray Atkinson :

both are log base 2

Customer:

yes

Ray Atkinson :

Excellent. Continuing

Ray Atkinson :

Whoops. First 20 are done. Do you want them, or all 40 at once?

Customer:

Ray Atkinson :

can I just give the answer letters here?

Customer:

sure

Ray Atkinson :

1. \$133,995.47
2. \$134,880.24
3. y=x-7/-2
4. Yes
5. No
6. 2.5422

Ray Atkinson :

6 and 7 again. Is #6 log7 55, and is #7 log17 205?

Ray Atkinson :

Question 18 does not have an answer.

Ray Atkinson :

x=3 is the answer, but not one of the choices.

Ray Atkinson :

It is a typo?

Ray Atkinson :

I have the other 19 done.

Customer:

6 is log7 55 and 7 was log 17 205

Ray Atkinson :

Good. I got them right

Customer:

18 is

Solve this exponential equation to the nearest hundredth:

2^x+1=9

 x = 2.17 x = 8.00 x = 1.65 x = 3.17
Ray Atkinson :

2^x + 1 = 9
2^x = 8
2^3=8 so x=3

Customer:

thank you so much, i wish i was as smart as you to understand this stuff. i wanted see after your done if Could answer the next questions if I paid more?

1. Here is the formula for compound interest: A=P(1+r/n)^nt
Describe what the parameters A, P, r, n and t represent and give an example to show how to calculate compound interest using this formula.

2. The "Present Value" of a compound interest account is the amount of money you need to invest in the account today to accumulate A dollars. You can calculate Present Value by solving for P in the compound interest formula above.

Calculate the Present Value (what you would need to invest) if you wanted to accumulate \$10,000 by investing in an account for 8 years that pays 6% interest compounded monthly.

If you'd like, pose some other Present Value problems for the class to solve.

3. As the number of times you compound the interest per year increases, the interest also increases. However, it will never be greater than the following formula for "continuous" compound interest: A=Pe^rt

Use the compound interest formula and the continuous compound interest formula to answer the following question:

You just won \$150,000 in the lottery and you decide to invest the money for 20 years to save for your retirement. However, you only get to choose one of the 4 options below. Which one would you pick and why?

1. A certificate of deposit paying 5.4% interest compounded annually?

2. A money market certificate paying 5.35% interest compounded semi-annually?

3. A bank account paying 5.3% interest compounded monthly?

4. A bank account paying 5.25% interest compounded continuously?

4. Explain step by step how to determine if two functions are inverses of each other. Provide a detailed example.

5. Give an example from real life where inverse functions are utilized. For ideas, look it up on the internet or find some examples in the textbook.

6. In your own words answer the following question - What is compound interest? What is the difference between compounded monthly and continuously?

Ray Atkinson :

Sure.

Ray Atkinson :

How much more?

Customer:

you tell me

Ray Atkinson :

\$6 ?

Ray Atkinson :

I will write it up at the end of the file I have for the other 20 questions.

Customer:

Customer:

ok thank you

Ray Atkinson :

I'll get done as fast as I can.

Ray Atkinson :

#\$5 might take me some time. Creativity is not my strong suit.

Ray Atkinson :

#5 I mean

Customer:

if you can't no worries

Customer:

i was thinking of machines

Customer:

can you send me the other 20 or do you not have them done yet

Ray Atkinson :

I have them. They are in the file I am doing the extra 6

Customer:

got it

Ray Atkinson :

except for that #19 that is wrong.

Customer:

19 is Solve this exponential equation to the nearest hundredth (using a calculator as needed).

3e^x-1=17

 x = 6.00 x = 0.78 x = 1.79 None of the above
Customer:

i thought you said 18 was wrong

Ray Atkinson :

Eep. you're right.

Ray Atkinson :

I'm on #4 of the last 6

Customer:

now 18 is Solve this exponential equation to the nearest hundredth:

2^x+1=9

 x = 2.17 x = 8.00 x = 1.65 x = 3.17
Customer:

Ray Atkinson :

Compound interest and annuities are fun equations to run

Customer:

if you say so lol

Ray Atkinson :

try this one on your own sometime. \$80 per month at 4.5% for 40 years.
80((1+0.045/12)^(40*12)-1)/(0.045/12)

Customer:

i will do my best

Ray Atkinson :

Just putting \$80 in the bank each month for 40 years, you will have \$107292.05

Customer:

i miss the class room for sure.

Ray Atkinson :

less than \$40000 of that is your deposits. Almost \$7000 is interest.

Ray Atkinson :

\$70000

Ray Atkinson :

Interest is a beautiful thing....unless you are the one paying it.

Ray Atkinson :

Ok, back to #4

Customer:

i should have started that when I was 10 lol thats a lot of money

Customer:

sorry i will stop

Ray Atkinson :

no need to stop. I like to chat when I am working.

Ray Atkinson :

It sure is a lot of money.

Customer:

yeah but i have to be up for work four hours from now and i have been up for over 19 hours

Ray Atkinson :

Oy. Get some sleep. I will be done soon.

Customer:

i would like to know if i can ask for you again in the future

Ray Atkinson :

You can put "For Ray Atkinson" at the beginning of your question any time.

Ray Atkinson :

no one else will take it. We are a very ethical bunch.

Customer:

oh i can't go to bed until i get this done since i will be away from computer for the most of tomorrow.

Ray Atkinson :

Ok. Quick.

Customer:

thats awesome thank you

Ray Atkinson :

Ok. I am done except for #5. You had an idea about that?

Customer:

yes thank soooooooooo much

Ray Atkinson :

I have not posted the answer.

Ray Atkinson :

...and I found an example for #5

Customer:

yeah

Ray Atkinson :

Let me upload the file, and then you can rate.

Customer:

ok with pleasure

Ray Atkinson :

Enjoy it...and get some sleep!

Ray Atkinson :

I'm going to go get horizontal and count the inside of my eyelids myself.

Customer:

thank you again and hopefully speak with you next time. sweet dreams
